The function also adds one to the mask matrix to get the right values for the net: of partGenerator partGeneratorData =īefore training for a lot of data is always good to try first with a small set. In order to do so it takes partitions of the whole dataset in batches of size BatchSize and load the element of this partition taking the module of the AbsoluteBatch. PartGenerator associate and load a batch of size BatchSize into the net training. The function can depend on the batch size, which can be set or set automatic by the computer, the absolute batch that is the number of batches load during the training and the round. NetTrain] calls f at each training batch iteration, thus only keeping a single batch of training data in memory. In the example above, I chose the custom option and. There are four preset size optionssmall, medium, large, and phoneand a custom option in which you can enter any dimension. This will bring up the utility’s options window.
#BATCHMOD IMAGE GENERATOR#
The generator function load a single batch of data from an external source to train each time. With Image Resizer for Windows installed, I can select all of the files, right-click, and select Resize Pictures. In order to train the net with a big amount of data a generator function was created.
